One Great Idea: Philadelphians' free Q & A with Doctors

In July, Jefferson University Hospital spine surgeon Alexander Vaccaro threw in his contribution to Philly.com's One Great Idea initiative - a medical town hall meeting, where Philadelphians can ask a panel of doctors anything, cost- and appointment-free.

His idea became a reality Thursday, when Vaccaro and three other doctors tackled questions from 30 people for an hour and a half in a brightly colored room of North Philadelphia's YouthBuild charter school.

The intimate event gave Vaccaro, also vice chairman of the department of orthopedic surgery at the Rothman Institute, a snapshot of the health issues Philadelphians care about: obesity, diet, high blood pressure, their children's well-being, and teen pregnancy.
